我希望你帮我准备一份详细的客户报表报告

Question

报告的目的是提供客户的详细帐户，显示两个日期之间每次交易后的余额以及开始日期之前的余额

我有一个来自 SQL Server 中三个表的视图。我想在开始和结束日期的三个基础日期从中提取证据。但是，以前的余额会在报告开头显示在客户端上。知道视图中没有余额列怎么能做到这一点。 我使用存储过程

我希望报告输出是这样的

我使用这个代码，但我有问题

declare @id_customer int 
;with initial as(
  select *
  from result
  where id_customer= @id_customer
),report as(
  select r.id,[balance]=isnull((select sum(b.debit-b.credit)
               from initial b
               where b.[date]<r.[date]) + r.debit - r.credit ,r.debit-r.credit)
  from initial r
)

 select [Operation type] = type,
        reference_no = r.id,
        [description],
        [Debit] = debit,
        [Credit] = credit,
        [Balance] = b.balance
 from result r
 inner join report b on b.id = r.id
 where r.id_customer = @id_customer
 order by r.[date]

一些记录来了

试试这个，没有示例数据很难猜测，但应该可以。 我假设事务 ID 是增量的，如果我错了，请纠正我：

declare @id_customer int = 2
;with initial as(
  select *
  from result
  where id_customer= @id_customer
),report as(
  select r.id,[balance]=isnull((select sum(b.debit-b.credit)   
   from initial b   
   where b.[date]<=r.[date] and b.[id]<r.[id] ) +
   r.debit - r.credit ,r.debit-r.credit),r.date

  from initial r

)

 select [Operation type] = r.type,
        reference_no = r.id,
        [description] = r.description,
        [Debit] = r.debit,
        [Credit] = r.credit,
        [Balance] = b.balance,
        [Date] = r.date
 from result r
 inner join report b on b.id = r.id
 where r.id_customer = @id_customer
 group by r.id, r.type,r.debit,r.credit,r.date,r.description,b.balance
 order by r.[date]
